摘要： The present invention provides a molding sheet material having a sandwich structure produced by preparing a fiber reinforced thermoplastic resin layer (A) reinforced with a woven fabric or a knitted web and a fiber reinforced thermoplastic resin layer (B) reinforced with a random mat and using the layer (A) as a core layer and the layer (B) as a skin layer, or using the layer (B) as a core layer and the layer (A) as a skin layer. When this sheet material is molded into a three-dimensional structure, the layer (B) serves as a cushion to prevent the occurrence of a wrinkle or a crease in the layer (A). A toe puff for a safety shoe having a light weight and excellent pressing resistance can be prepared through the molding of this sheet material. In the sheet materials, the core layer or the skin layer consisting of a thermoplastic resin reinforced with a woven fabric or a knitted web of a reinforcing fiber may be prepared from a woven fabric or a knitted web of a reinforcing fiber alone.
